Air Preparation Units | FRL Filter-Regulator-Lubricator (SOLH by Richge Technology)

     Brand: SOLH by Richge Technology (睿其格科技)

     Brand Advantage: SOLH FRL units are fully interchangeable with SMC and AirTAC original models, modular design for free combination, serving as the front-end core protection for all pneumatic systems.

Overview

     FRL units (Filter-Regulator-Lubricator) are essential front-end components for pneumatic systems. Installed at the air compressor outlet, they filter moisture, dust and oil contaminants, stabilize air pressure and provide micro oil mist lubrication. Effectively preventing valve sticking, seal abrasion and cylinder jitter, they greatly extend the service life of downstream pneumatic components and reduce equipment failure rates.

SOLH offers compact A series and high-flow B series with port sizes from G1/8 to G1/2. Multiple drain modes are optional to adapt to diverse industrial scenarios, supporting oil-free and lubricated air circuit requirements.

Main Product Series

1. Single Individual Modules

• AF / BF Air Filter (F)：Removes condensed water, rust and solid particles. Standard 5μm filtration; optional 0.3μm high precision for vacuum and proportional valve systems. Equipped with manual, differential and float automatic drain modes. B series comes with impact-resistant protective cover, water separation efficiency ≥95%.
• AR / BR Pressure Regulator (R)：Stabilizes fluctuating compressor pressure to ensure constant cylinder output thrust. Adjustable range: 0.05~0.9MPa, with vibration-proof lockable knob. Compatible with external pressure gauge and wall mounting bracket.
• AL / BL Lubricator (L)：Atomizes ISO VG32 pneumatic oil to form uniform micro oil mist for valve and cylinder seal lubrication. Visible adjustable drip window and anti-backflow structure avoid oil reflux after shutdown.

2. Combined Assembly Units

• AFC / BFC 2-Unit (FR Oil-Free Type)：Filter + regulator without lubricator, specially foroil-free environments: 3C electronics, food machinery, vacuum handling and PU hose piping systems.
• AC / BC 3-Unit (FRL Standard Type)：Complete filter-regulator-lubricator integrated unit, the standard configuration for machine tools, stamping and packaging equipment to realize one-step air source purification, pressure stabilization and lubrication.
• Main Models: AC1500, AC2000, BC3000, BC4000

3. Supporting Accessories

     Pressure gauge, mounting bracket, replacement filter cotton, bowl protective cover, auto drain valve, residual pressure relief valve.

• Mini Jig System: AC1500 FRL → 3F foot valve → MAL mini cylinder
• Workstation Main Air: BC4000 high-flow FRL → HSV shut-off valve → 4F foot valve + C110 blow gun
• Pipeline Valve Control: AFC3000 FR → 4M NAMUR valve → Pneumatic actuator

Application Industries

     CNC machine tools, 3C electronic automation, food packaging, new energy equipment, pharmaceutical clean workshops, logistics sorting lines, stamping & riveting fixtures and water treatment systems.

Selection & Maintenance Notes

• Choose 2-unit FR for vacuum circuits, PU hose systems and food-grade oil-free equipment; adopt 3-unit FRL for heavy-duty and high-frequency pneumatic circuits.
• Select manual drain for easy-access positions; auto drain for unattended automated lines to avoid water accumulation.
• 0.3μm high-precision filter is required for proportional valves and precision vacuum systems.
• Install strictly in F-R-L sequence with bowl downward; drain water regularly and replace filter cotton periodically to ensure air source cleanliness.
